Working Group 3: Impact Engineering - New Helmet Impact Conditions

Article Index

New Helmet Impact Conditions

Current testing is shown to be deficient in three key areas. First, it does not include testing for impacts at an angle, although the majority of accident data indicates that angled impacts are common and cause significant injury. Second, testing does not currently account for realistic brain injury criteria, despite the fact that this is shown to have an effect on impact conditions. Third, data is available to analyse the impact location on the helmet after an actual accident. This data indicates that the testing line defined in EN 1078 is too high. Working Group 3, in conjunction with Working Group 1, therefore proposes to lower the test line, so that the helmet covers more of the head, whilst still creating a design that is attractive and accepted by the end consumer.

Working Group 3 proposes new test methods for improving testing in bicycle helmets from these three critical points of view. First, impact testing to accommodate the 45-degree-angle impact condition. Second, testing to account for the effect of a more realistic pass/fail criteria. The third testing improvement would be to lower the testing line for the impact location on the helmet.
